    Abstract: 本文以具有流固耦合功能與動態邊界設定之COMSOL Multiphysics商用軟體，進行三拍翼編隊的非定常流場模擬與升力評估。拍翼翼展20公分，翼弦6.5cm，PET材質，拍翼頻率14 Hz，流速範圍2-4 m/s，並嘗試兩種三拍翼編隊的位置。完成一個三拍翼10個拍翼週期的計算案例，約需496小時33分。模擬結果初步顯示：(1)經過3個拍翼週期，升力有收斂趨勢，流速2 m/s的表現較為穩定。(2)在未找到較佳的編隊位置之前，三拍翼的單隻平均升力仍小於單隻拍翼。(3)編隊的前後/側向距離，若與拍翼翼展/翼弦尺寸有公倍數關係，升力較佳。(4)編隊位置妥適性，可先從領頭拍翼升力得知端倪。
